Screw clamp for hanging the hook of a lever block when building vessels and manufacturing(attachment and press) construction plants and also for horizontal lifting during the press process.
Efficient ratchet pushers which are convenient and quick to work with when assembling frames(outer plating and middle wall) to the inner(bottom) plating in ship assembly shops.
The NPR-PA is the combination of a ratchet pusher and a screw clamp and it is an efficient clamp shortening the multiple-step working process, leading to higher productivity.(Previous process: Fix the HYD'JACK. support piece to the inner plating by electric welding. Remove the piece after completing the work.)
The NPR-PA is used to push inward the interval of frames whicha re installed at the end part of the inner plating.
Since different models of the NPR-PA(PA1, PA2, PA3) are used depending on the left and right end parts of the inner plating, accurately select a model according to the worknig condition.
The NPR-PA2 is used in attaching two work pieces on a flat work plate by pulling or in widening the interval of work pieces by pushing.
The stopper type has the built-in pin to prevent the screw from completely coming out of the pipe.
How to Use
After setting the ratchet pusher between frames to be tack welded and tack welded frames(L- and T- sections), push up or down the pawl according to purposes and then operate the handle.
Do not exceed the rated capacity specified on the ratchet pusher.
